Description

TECHNICAL FIELD [0001] The present invention relates to an in-line manufacturing system, an in-line manufacturing method, an organic film device, and a donor substrate set for an organic light-

The present invention relates to an in-line manufacturing system, an in-line manufacturing method, an organic film device, and a donor substrate set of an organic light emitting device, more specifically, to assure uniformity of a deposited organic film, In order to improve the productivity by reducing the TACT time, an in-line manufacturing system of an organic light emitting device for depositing an organic film layer on an element substrate using two donor substrates and an organic film deposition process, an inline manufacturing method, Donor substrate set.

Among the flat panel display devices, the organic light emitting display device has a response speed of 1 ms or less and has a high response speed, low power consumption, and self light emission, so there is no problem with the viewing angle, . In addition, since it can be manufactured at a low temperature and the manufacturing process is simple based on the existing semiconductor process technology, it is attracting attention as a next generation flat panel display device. In addition, since the organic layer used in the organic light emitting display device emits light by itself, it can be used in an OLED lighting device by applying an electric field to the upper and lower ends of the multi-layer organic film after the entire deposition. OLED lighting is a point light source, while LED light is a point light source.

The formation of the organic thin film in the organic light emitting display device and OLED lighting manufacturing process can be broadly classified into a polymer type device using a wet process and a low molecular type device using a deposition process depending on the materials and processes used. For example, in the case of an inkjet printing method among the methods of forming a polymer or a low molecular weight light emitting layer, the materials of the organic layers other than the light emitting layer are limited, and there is a need to form a structure for inkjet printing on the substrate. When a light emitting layer is formed by a vapor deposition process, a separate metal mask is used. In a metal mask, the size of the metal mask must be increased as the size of the flat panel display increases. At this time, There is a problem that it is difficult to manufacture a large-sized device.

On the other hand, a technique of forming an organic light emitting layer by using line heating has already been disclosed. In this technique, an organic light emitting layer is first formed on a donor substrate, and then the donor substrate and the element substrate are positioned to face each other. Then, the row heat is heated on the donor substrate to deposit an organic light emitting layer formed on the donor substrate as an element substrate.

However, the technique of forming the organic light emitting layer using the row heating has a problem in that the process time (TACT time) increases due to the addition of unnecessary processes such as the inversion of the donor substrate or the device substrate.
